If "E1" appears on the display, the system cannot easily
measure the vehicle−to−vehicle distance because of a dirty
laser radar sensor glass while the dynamic laser cruise control
is on.
If this code appears, clean the sensor glass with a soft cloth
and try setting the preset speed again. If the dirt is removed
without cleaning, the system will automatically enter the ready
mode.
If the system does not enter the ready mode even after
cleaning or the code remains on the display, the system might
be malfunctioning. Although there is no problem to continue
driving, please contact your Lexus dealer.
CAUTION
Always keep the sensor glass clear and never allow it to
be covered with icicle or any substance, so it can detect
the vehicle in front.
